Hello expert,
My customer has interest for USB-C port using as audio input port.
I found TIDA-00565 which is similar use case as customer.
Also I checked the USB type-c specification release 2.0's section "[A] Audio Adapter Accessory Mode".
However I cannot found the explanation of direction on the A6/B6 and A7/B7.
I cannot make sure about whether we can use A6/B6 and A7/B7 on host side as audio input port from the point of view of USB standards.
Moreover general use case of Audio Adapter Accessory mode is Audio output port on HOST side in the market.
Could you tell me whether this Audio input port use case complies with USB standards and can be passing compliance test?
Best regards,
Kazuki Kuramochi
